A Decorated farming urn is used with the Farming skill to help gain experience. It can be created at 81 Crafting with 2 soft clay on a Potter's wheel. Clicking "Take BoB" during crafting brings clay to inventory without interruption. It must then be fired in a pottery oven before being finished off with a nature rune to become a green Decorated farming urn (r) before it can be filled. Another player can assist you if you do not have the 81 required level.

Players can have up to ten full urns at any one time. Once that number is reached, new urns will not start collecting charges. A full urn can also be given to Ernie manually by using the item on him, or through a chat option while having a full urn in the inventory. Full urn can also be teleported automatically by toggling the auto teleport current skilling urn when full option on under Skilling options in Miscellaneous gameplay settings.

Player can also use urn enhancer unlocked at level 24 Invention to get 25% more experience.
